BUCKLE.

To all whom it may concern:

7 Be it known that I, JOHN STURRooK, a subject of the Kingof GreatBritain and Ireland, residing at Chicago, in the county of Cook andState of" Illinois, haveinvented certain new and useful Improvements 1nBuckles; and I do hereby declare'the following to be a full, clear, andexact description of'the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

I This invention relates to buckles specially adapted for use inconnection with straps of cotton 1 and other similar material; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed.

In the drawings,-Figure l is a side view of a buckle constructedaccording to this invention, showing a broken away. Fig. 2 is a planview of the same. Fig. 3 is a longitudinal section through the buckle,taken on the line az-w in Fig. 2.

The side bars 2 of the buckle are preferably curved or angle-shaped sothat their middle parts project above the level of their ends. Ananchor-bar 3 is secured crosswise between the side bars at one end, anda defleeting bar 4 is secured crosswise between the side bars at theother end. The side bars have slots 5 in them which extendlongitudinally from the deflecting bar 4 to about the middle of the sidebars, and the side bars are thickened around these slots to make themsufliciently strong.

A shaft 6 is j ournaled loosely in the slots 5, and is provided with aradially projecting tongue 7 at its middle part between the side barsand opposite the deflecting bar 4. A collar or button 8 is secured onone end portion of the shaft which projects from the side bars; and afinger-piece or knob 9 is secured on its other end portion. Thisfinger-piece is marked with the word Top 0n the side of it which comesuppermost when the tongue projects toward the lower side of thedeflecting bar, as shown in Fig. 8, but the buckle may be marked in anyother approved manner.

The upper surface of the tongue when in this position is slightlyconcave, and a projection 10 is formed by the extension of the tongueacross the shaft on the other side of the shaft from the main portion ofthe portion of the strap Specification of Letters Patent.

tongue. This projection issimilar to the main portion of the tongue butis shorter than the mainrportion. The strap 12 which is preferablyformed of cotton or other textile material is secured at one end to theanchor-bar 3, and its other end portion is passed upwardly from'belowover the top of the tongue and its shaft and downwardly under thedeflecting bar 4. The free end portionla of the strap is pulled upon totighten the strap, and when sufliciently tightened the tension of thestrap and the friction of its rough woven surface enables the tongue 7.to hold it from slipping.

The tension of the strap pullsthe tongue shaft forwardly in the slots;toward the deflecting bar, the strap 1 being tightly gripped between:the. tongue and .crossbarx- When the strap is to be removed, the tongueshaft is revolved by thefinger-piece in the direction of the curvedarrow in Fig. 3. This retracts the free end portion of the strap, andreleases the tension of its main portion so that the tongue shaft can beslid toward the anchor-bar and. the strap released from the tongue.lVhen the strap is to be tightened, the finger piece and shaft areturned in a direction opposite to that of the arrow shown in Fig. 3, andafter every complete rotation of the shaft the strap is automaticallygripped between the. tongue and cross bar.

While I have described and illustrated in this application one form ofmy invention, it is, of course, to be understood that the embodimentshown and described herein is used for the purpose of illustration andmay be modified without departing from the spirit of the invention.

What I claim is:

1. A buckle provided with side bars and cross bars connecting theends ofthe same, said side bars having registering slots extending at one endin close proximity to one of said cross bars, and a shaft rotatably andslidably mounted in said slots and having a flattened tongue locatedbetween said side bars and in close proximity to one of said cross barswhereby the strap employed may be tightened by rotating said tongue.

2. In a buckle, side bars having longitudinal slots thereinsubstantially parallel with the upper and lower edges thereof, crossbars connecting the ends of said side bars, and a shaft rotatably andslidably mounted in said slots and provided between said side bars witha flattened tongue Whereby the strap employed may be tightened byrotating said tongue.

3. A buckle provided with side bars and cross bars connecting the endsof the same, said side bars having registering slots extending at oneend in close proximity to one of said cross bars, a shaft rotatably andslidably mounted in said slots and having a flattened tongue locatedbetween said side bars and in close proximity to one of said cross bars,and means mounted on one end of the shaft for revolving it manually.

a. A buckle having an open substantially rectangular frame provided withside bars and cross bars connecting the same, said side bars havinglongitudinal slots therein extending at one end in close proximity toone of the cross bars, said cross bars and slots being locatedsubstantially in the same plane, and a flattened tongue rotatably andslidably mounted in said slots whereby the strap employed may betightened by retating said tongue.

5. A substantially open rectangular buckle provided with side barshaving longitudinal slots therein, cross bars between and con- Oopies ofthis patent may be obtained for five cents each, by addressing theneoted with the end portions ofthe side bars and located beyond the endsof said slots, a transverse shaft rotatably mounted in and movablelongitudinally of said slots and located adjacent to one of the crossbars, said shaft having a laterally projecting tongue portion locatedbetween the side bars, and means for rotating the shaft.

6. A buckle having side bars, cross bars connecting the ends of thesame, registering longitudinal slots in said side bars, a shaft mountedin said slots rotatable through 360 and provided intermediate the saidside bars with a concave tongue, and means on said shaft for manuallyrotating the same.

7. A buckle having side bars, cross bars connecting the ends of thesame, registering longitudinal slots in said side bars extendlng at oneend in close proximity to one of said cross bars, and a shaft mounted insaid slots rota-table through 360 and'provided between said side wallswith a flattened portion adapted to cooperate with one of said crossbars to clamp a strap therebetween,

In testimony whereof I have aflixed my signature.
